The FN FNX-45 Tactical is a hammer fired semiautomatic, short recoil operated pistol chambered in .45 ACP. The FNX-45 Tactical is modeled after the FNP-45 which was FN’s service pistol that was submitted to the U.S. Joint Combat Pistol Program in 2007. Featuring a stainless steel, cold hammer forged barrel, the FNX Tactical was built to last and can fire thousands of rounds before needing a replacement. What sets the FNX-45 Tactical apart from the base model FNX-45 is the threaded muzzle which can readily accept suppressors, compensators, or various other aftermarket accessories and suppressor height tritium night sights (rear yellow/front green) are standard. The tactical version also comes with two 10-round magazines. The stainless-steel slide has been modified to accept multiple types of optics with two mounting plates included with each pistol. This FN firearm is equipped with various ambidextrous controls such as the magazine release, safety/decocking lever, and a slide stop release lever. Interchangeable backstraps with lanyard eyelets are included to provide ergonomic customization to the user. This accommodates left and right-handed shooters. FN Herstal/ FN America has been manufacturing quality firearms for over 125 years which include firearms issued to the U.S. Military. If you are looking for a quality, suppressor-ready .45 pistol that can be used at the range, lawfully carried, or for home defense, the FN FNX is the right choice for you.

The FNX-45 Tactical also has a MIL-STD 1913 Picatinny rail for attaching flashlight, lasers, or other accessories. A loaded chamber indicator adds an extra safety feature and tritium night sights make the sights visible in all kinds of lighting conditions. What makes this FN pistol different from other manufacturers is the distance of slide travel and barrel prior to the barrel dropping and unlocking. The barrel and slide travel almost up to twice the distance of competitors before unlocking which means the spring can absorb more momentum of the barrel and slide. This helps the user feel a reduced amount of recoil while shooting. A loaded chamber indicator adds an extra layer of safety for the shooter. The FN FNX-45 Tactical in .45 ACP ships with two 15-round magazines. With an over 127-year history, Fabrique Nationale stands at the cutting-edge of quality commercial, law enforcement, and military weapons.
